Quartz conducted tests which showed that any photograph posted to Instagram when a user’s account is set to public—the default setting—would remain publicly viewable on the web, even if the user made her account private. This flaw also affected the photos shared on other social media sites that were shared through Instagram as the image’s URL was exposed.
